Interesting. This actually relates to what I'll soon have to work around. I currently have RBP (light) installed, in which adds no extra races or cosmetics, just birth signs and stats. I then plan on installing http://www.tesnexus.com/downloads/file.php?id=16988 and here are its requirements...
Requirements:
1. Capucines Character Expansion - http://www.tesnexus.com/downloads/file.php?id=3934
2. The "coreanhair" file from the Corean mod - http://www.tesnexus.com/downloads/file.php?id=15568
3. Ren's Beauty Pack - http://planetelderscrolls.gamespy.com/View.php?view=OblivionMods.Detail&id=1011
So, I'm curious if these required mods (especially Ren's Beauty Pack that is known to be included beautiful people) will give me grief as well, just because I have RBP installed.
Oh, and sorry to barge in on your thread...
1. RBP covers most of those resource files.
2. Just don't install the plugin.
3. Capucine's mod includes Ren's resources. In fact, that was the first mod I switched to from Ren's Beauty Pack (after being disappointed by BP.)
Edit: I'm verifying whether or not my memory has completely failed. I have used all of the mods in question. I just need a sec to download Cap's mod again.
Edit: Okay, I have partially lost my mind. Cap's mod does not include Ren's files. I was mixing it up with the Cosmetic Compilation. Bad, I know... However, RBP includes Caps' eyes. Therefore, installing it would, yet again, be a waste. Just install RBP and the Corean hair mod, and things should be fine. Actually, if that mod uses the Ren's hairs with bandanas and whatnot, you'll need to install at least the hair resource from Ren's mod.
